Fluke PRV240FS Ověřovací jednotka

Fluke Proving Unit, 240V Output Voltage, Battery Power Source - PRV240FS

This proving unit is a compact, battery-operated voltage source intended to confirm the correct operation of no-test-lead FieldSense measurement and other high-impedance instruments in industrial environments. It supplies a steady 240V AC or DC output to allow technicians to perform a test-before-touch sequence, reducing exposure to live systems while validating measurement tools prior to and after on-site measurements.

Features & Benefits

• Supplies 240V AC or DC to validate instrument response under load
  LEDs indicate presence of output voltage for immediate verification
  Operates from four AA alkaline cells for field battery convenience
  Performs approximately 2,000 tests per battery set to reduce downtime
  EMC meets IEC 61326-1 and CISPR11 for industrial electromagnetic environments

**Applications**

• Suitable for proving FieldSense functionality on T6 electrical testers
  Ideal for use with high-impedance multimeters and clamp meters
  Used for pre-measurement verification in electrical maintenance routines
  Can be used for factory test benches requiring a portable voltage source

How is the output presented for different tester types?

The unit provides voltage via a central hub for open-fork FieldSense checks and through recessed contacts that activate when probes are inserted for conventional probe-based instruments.

What environmental conditions will it tolerate during typical use?

It operates between -10°C and 50°C, with humidity limits that vary by temperature: up to 90% relative humidity from 0°C to 35°C, and up to 70% from 35°C to 55°C.

What measures reduce accidental contact risk during testing?

Recessed probe contacts prevent inadvertent touch, and a simple single-switch operation minimises handling complexity during verification.

How portable is the unit for field technicians?

The device weighs 0.32 kg including batteries and includes a magnetic hanging strap for convenient hands-free placement.

Which approvals indicate suitability for industrial use?

It conforms to IEC 61010-1 and IEC 61010-2-030 safety standards and is classified under CISPR11 and related EMC regulations for industrial equipment.
